Abstract
A wave generator of a flat-type strain wave gearing has an insertion member disposed between two wave bearings. The insertion member is pressed into an elliptical outer peripheral surface of a plug and is fixed thereto by an adhesive. An inner ring contact part of the insertion member is in contact with inner rings of the wave bearings from the direction of a center axis. When the flat-type strain wave gearing is in an operating state, the wave bearings can be prevented from moving relative to the plug in the direction of the center axis by means of thrust force acting on the wave bearings.
